Guidance and navigation programs and plans

System technology concepts for all weather helicopter operations in both remote and high density areas were examined. The SH-36 was used to support the remote area investigations. The primary emphasis was on the development of advanced navigation concepts to allow rotorcraft to land in remote areas where there may not be a ground based navigational aid. The focus was on the used airborne weather radar, the use of high resolution radar and satellite based navigation concepts. The high density work was conducted using the UH-1H system that allows alternate guidance and navigation algorithms to be tested in flight.
